Connect through 3G
The chumby One contains a copy of pppd, and contains hidden hooks to allow you to connect through a 3G dongle. We have tested both CDMA and GSM cards, and while most of them work, some may require custom pppd scripts (like Japanese Willcom cards), or special udev events to eject virtual CD drives (like some Verizon dongles), or eve other hacks.
GSM users will first need to set up a config file. CDMA users can most likely skip directly to creating the 3G connection.
Configuring GSM Connections
GSM connections require several pieces of information: APN, username, password, and phone number. For most GSM networks, the number will be *9***1#, but the username, password, and APN are network-specific. You should find a list of APNs for your specific network.
Once you know your apn, username, password, and number, connect to your chumby via wifi, ssh, or by plugging in a keyboard, and create the file /psp/3g_config. It is an XML file that contains nodes for each of these four pieces of information, and is structured in a manner similar to that of the network_config file. An example file for Emobile Japan would look like:
<configuration apn="emb.ne.jp" username="em" password="em" number="*99***1#"/>
Since this file resides on the persistent storage partition, it will persist across reboots and network connections even if you update the software or switch networks. Only restoring to factory defaults will remove this file.
Creating the 3G Connection
Follow these steps to create your network connection and get connected via 3G for the first time.
- Plug in your 3G card.
- Go to the Network Config screen by pressing the top button, going to Settings, then tapping on Network.
- Select "create a new connection", press OK, and wait for the scan to time out.
- Select "Other"
- Enter 3G as the name of the access point. It must have a capital G for it to work.
- Wait for the subsequent scan to time out.
- Select "Manual".
- Tap "OK" to select None as the encryption type.
- Tap "OK" to select Automatic IP allocation.
- Tap "OK" to confirm settings and connect to the network
If all went well, you should be connected over 3G. Additionally, you should now have a 3G network connection that you can switch to whenever you want to plug in your 3G card listed alongside your other network connections.
